IMPROVEMENT IN FLOWS. i

Specification forming part of Letters Patent No. 145,862, dated December23, 1873; application filed January 27, 1873.

To all whom fit may concern:

Be it known that I, JOHN LINDsEY GRA- HAM, of Carthage, Illinois, haveinvented a new and useful Improvement in Blows, &c., of which thefollowing is a specification:

This invention relates to cultivators for corn and otherplants; andconsists of the features made as hereinafter set forth, referring totheaccompanying drawings, in which- Figure l is a top view or plan of themachine 5 and Fig. 2 is a side View of a portion ofthe same. Fig. 3 is aview of the joint.

This invention belongs to the class of cultivators designed to act onboth sides of a row at one passage. To the tongue A, between the horses,is attached a frame, B B', having side parts C C', which bear wheels DD', on which the weight rests. To the part B, at a point in front of thewheels, the ends of the plow-beams E E' are attached by means ofpendants F F', adjustable in height and position. The beams are attachedto the pendants by means of 'double hinge-joints, that give free lateraland vertical motion. These joints are made of a top and bottom piece,like G, to clasp the end of the plow-beam. They are fastened thereto bythe bolt H, acting as a pivot for the beam. These parts G are connectedtogether by bolts G1 G2, and around these are bent the ends of parts II', which project forward, clasping the pendant F, Fig. 3, to which theyare secured by the bolt I2, acting as a hinge for the vertical motion.The tongue and frame BB' are elevated to pass over the row of plants,and an evener, K, is pivoted to the tongue in the center. At the sides,parts K1 K2 descend,

by the side of parts C C', to a suitable height,

and the horses are attached to their lower ends. These parts K1 K2 arepivoted to parts C C' in their centers, and are attached to part K bylinks at their upper ends, so as to complete the evener. The beam Ebears eight teeth or small plows, arranged as shown, to cut the soilfinely in cultivation. Two of them, G C', are arranged forward, on cachside of the beam. The others, M M' N N1 N2 N 3, are arranged back ofthem, on a frame, O, on each side of the beam. The tooth M is arrangedto run close to a row of plants on the line l), and others follow atsuccessive distances. The tooth M' runs near the middle, between tworows, and just back of, or outside of, the line of the wheels, thearrangement of the whole being such as to thoroughly pulverize the wholespace, and that the clogging up of one will not unduly help in cloggingthe others. The beam is guided by the handle Q. The teeth are made of ashape t0 do good work and avoid clogging. The plow point or shoe Rprojects forward from the upright part Bl, to enter the soil. The toothhas a backward bend, R2, to throw off trash, and avoid clogging beforereaching the frame O, to which it is attached. It is fastened, by boltsS S', at the bottom and top of the frame.

If the tooth is inclined to run too deep, a wedge is put behind thetooth at the bottom; if too shallow, the wedge is put in at the top.

I claiml. The teeth R Bl R2, constructed in the form shown, and attachedto the frame by bolts S S', arranged as and for the purpose specied.

2. The beam E, provided with the teeth L L', and the frame O, providedwith the teeth R R1 B2, all constructed and arranged for op eration asand for the purpose set forth.
